thanks for looking out. I was also thinking bisi was a little sketch because of what i have read on other forums about it........the only article i could find with all of the d16 cams had bisi 2.4 cam out doing his 3.4 race cam by 3hp (done in the same car, same motor, ect. the only thing that was changed was the cam and timing of course) that to me had me scratching my head because the 3.4 cam is the one in his 700hp sohc......I have decided to go with the crower stage 2 and see what happens. I am contemplating if i should go ahead and sleeve the block or just get some mad head work done and see how long i can make the sleeves take it. bc like i said i should easily put down 350hp to the wheels or really close to that bc any more than that on the street and the tires would continously be blown off to 60mph+ no good if i am not hookin.
